2. Let's imagine that we are studying only one trait, that of green- or yellow-colored seeds. Mendel bred his peas until they either produced seeds of one color or the other. These purebred plants he called the p generation ("p" for parental generation). He then cross bred green plants with yellow ones and discovered that all the offspring were yellow-colored. Mendel called the offspring of the purebred plants the F1 generation.

Explain why all the offspring in the F1 generation were yellow instead of half being yellow and half green, or some other mix of the colors. Hint: Remember that Mendel coined the terms dominant and recessive.
